Technical Field

The invention relates to an aluminum casting of a suspension blower shell.

Background

Disclosure of Invention

The invention provides an aluminum casting for a shell of a suspension blower, which aims to overcome the defects in the prior art and meet the structural requirements of the suspension blower.

The technical solution of the invention is as follows: suspension air-blower shell aluminium foundry goods, its structure includes from last intake duct to connecting gradually extremely down, the spiral case, motor casing and back lid, wherein the intake duct is mutually perpendicular with the spiral case air exit, intake duct lower part circumference outwards is equipped with the first boss of round, the inboard circumference of spiral case inwards is equipped with the first step of round, the first boss of intake duct passes through the screw to be connected with the first step of spiral case, and first boss outer edge with the inboard cooperation joint of spiral case on first step upper portion, spiral case lower part circumference outwards is equipped with round second boss, the motor casing top outwards is equipped with round second step along the circumference outward, the second boss of spiral case and the mutual joint of second step of motor casing, the outside third step that outwards is equipped with along the circumference in back lid top, the third step of back lid passes through screw and motor casing bottom edge connection.

Preferably, the total height is 500.7mm, the total height of the air inlet channel is 166.5mm, the outer diameter of the upper part is 135mm, the outer diameter of the middle part is 106mm, the outer diameter of the lower part is 180mm, the height of the highest position of the volute is 104mm, the outer diameter of the air outlet is 114.3mm, the height of the motor shell is 247mm, the outer diameter of the top part is 322mm, the outer diameter of the bottom part is 240mm, the height of the rear cover is 69.5mm, the outer diameter of the top part is 240mm, the outer diameter of the bottom part is 210mm, and the outer diameter of.

The invention has the advantages that: a shell structure for suspension air-blower, its suspension air-blower does not need gear box speed increaser and shaft coupling, is driven by high-speed motor direct drive, and the motor adopts the converter to speed governing. The blower wheel is directly coupled to the motor, and the shaft is suspended on an active bearing controller. Because there is no physical contact and no need for a lubricating oil system, the suspension blower has the characteristics of high efficiency, energy conservation, low noise, reliable operation and no need for maintenance for a long time.
